● 100xAI · Day 5 of 10 · Week 1: Foundations

The everyday toolkit: Draft · Distill · Plan · Tabulate

Four days of foundations come together today. You can hold a real conversation (Day 1), brief like a pro (Day 2), you've picked a daily driver (Day 3), and you know how to check what comes back (Day 4). Now you hand the assistant your actual desk — the inbox, the documents, the week, the numbers. This is the Week-1 capstone, and it closes with your first module check.

The one-sentence definition

The highest-ROI uses of AI aren't exotic — they're your boring desk work. Master four verbs — Draft, Distill, Plan and Tabulate — and you've handed off the most annoying slice of your week.

1The honest secret of AI productivity: transformation beats generation

The demos that go viral are always the spectacular ones — an AI writing a novel, passing an exam, inventing a business plan from one sentence. But ask people who quietly use these tools every day where the time actually comes back, and the answer is almost embarrassing: replying to email. Summarizing a PDF they didn't want to read. Planning a week. Untangling a list of expenses. The boring, recurring slice of the week — call it the boring fifth, as a rule of thumb — that everyone has and nobody enjoys.

There's a deeper reason the boring work is where AI shines, and it's worth thirty seconds of theory because it changes how you'll use these tools forever. An assistant can work in two modes — and the difference is the whole lesson:

Generation
"Tell me about tenant rights."

Answers from compressed training memory — which has a cutoff date. This is exactly where confident mistakes live, and why the Three-Click Check from Day 4 exists.

Transformation
"Here's my lease — what's my notice period?"

Quotes the text you supplied instead of recalling. The facts are sitting right there in the conversation — so it's grounded.

When the assistant works from text you supplied, it is grounded — the single most useful safety concept in this course. That's why "summarize this attached report" produces dramatically fewer confident mistakes than "tell me about this topic." Same assistant, same day, completely different risk profile. The Confident Intern from Day 1 is at their absolute best when you put the folder on their desk instead of asking them to work from memory.

Two pieces of mechanics make transformation possible. First, pasting: anything you can copy — an email, a list, rows from your banking app — can go straight into the message box as part of your prompt. Second, the attachment: a file you add to the chat using the attach button (the paper-clip or + icon near the message box), so the assistant can read the whole document — a PDF, a Word file, a spreadsheet. Once it's in the conversation, you can ask anything of it, in that thread, for as long as the thread lives.

So here's today's reframe: stop thinking of your assistant as an oracle that knows things, and start thinking of it as a machine that transforms things. Your things. That one shift makes today both the safest day of the course so far and the most immediately useful.

2Meet the Four Desk-Work Verbs

Almost everything an everyday user gains from AI in a normal week falls into four jobs. We'll call them the Four Desk-Work Verbs, and they're the vocabulary for the rest of the course: Draft · Distill · Plan · Tabulate. Learn to recognize which verb a task belongs to, and you'll never again stare at the message box wondering what to type.

✉️
DRAFT
Words you owe someone
Emails, replies, messages, announcements, difficult notes — written around your situation, in your chosen tone.
Give it: the email you received + your real intentGet back: a sendable reply, in three tones if you ask
📄
DISTILL
Documents you don't want to read
Summarize a PDF, extract the deadlines from a contract, pull the action items from meeting notes — then ask follow-up questions of the same file.
Give it: your PDF or doc (the paper-clip)Get back: the 5 bullets that matter + answers from the text
🗓️
PLAN
Time, trips, projects, decisions
Turn commitments and to-dos into a realistic week; plan a trip, a move, a project — with buffer time and an honest "this won't fit."
Give it: fixed commitments + the task listGet back: a day-by-day plan you can push back on
🧮
TABULATE
Messy numbers and lists
Paste chaos — expenses, sign-up lists, copied receipts — and get a clean table, category totals, and the pattern you couldn't see.
Give it: the raw rows, copied as-isGet back: a clean table + totals + the top-3 story

Notice what every quadrant has in common: you give it something real first. All four verbs are transformation verbs — which is why this whole day inherits the safety profile of grounding from section 1.

Where each verb runs. Draft and Plan work beautifully in any of the big three — use your daily driver from Day 3. Distill and Tabulate love files, and that's where the staff model earns its keep: Claude is the file workhorse — it's generous with how many files you can attach to a chat, and on most plans it can even create files back, a clean document or spreadsheet you can download. ChatGPT's free plan caps daily file uploads, so it works for one-off documents but runs out fast. These limits change often — check the current limits on your own plan; if the numbers look different on your screen, the workflow still works the same.

The Distill pattern with a name: summarize, then interrogate. Beginners attach a document, get the summary, and leave. The real value is the second move: stay in the same thread and ask questions of the same file. "Which of these deadlines applies to me?" "Where exactly does it say that? Quote the line." The document is already in the conversation — every follow-up is grounded in it. A summary is a map; interrogation is the conversation with someone who has actually read the territory.

What "Tabulate" does and doesn't mean. Today is spreadsheets-lite, on purpose: paste in messy data and get clean tables, category totals, comparisons, and plain-language answers like "explain the formula I'd need to do this in my own spreadsheet." What it is not: macros, plugins, or the assistant reaching into your live files. That's a different skill for a different day — and you don't need it to get the wins that matter this week.

3Two habits that start today: the Prompt Notebook and the Privacy Line

Today your prompts start earning their keep — which means it's time to stop losing them. Find the note you started on Day 2 (in whatever notes app you use — Apple Notes, Google Keep, a plain document) and rename it Prompt Notebook. The rule is simple: every time a prompt works well on real material, paste it in verbatim, with one line about what it was for. Think of it as a recipe box, not a textbook — you're not collecting clever prompts from the internet, you're keeping the exact recipes that worked in your kitchen. The landlord briefing from Day 2's mission is entry #1, and Day 3's daily-driver verdict is entry #2 — fold it in if you haven't. By Day 9 this notebook graduates into repeatable workflows, and on Day 10 it seeds the "top 5 saved prompts" of your personal toolkit. Today you add entry #3.

And because real documents start flowing into chats today, this is also the day for the course's one privacy rule — calm, practical, and worth taping to your monitor. It's called the Privacy Line:

Don't paste anything you wouldn't email to an outside contractor.

An outside contractor is professional, helpful, and not part of your inner circle — exactly the right mental model for an AI assistant. So: no passwords. No full card or account numbers. No other people's private data — medical details, salaries, anything a colleague or friend would be upset to find outside your hands. And when a name or number isn't needed for the task, anonymize as you paste: the assistant can draft a perfect reply to your landlord without knowing the landlord's name is Anna Weber, and it can categorize your expenses without a single real account number. Swap them for placeholders like [Name] and [acct] — the result is identical, the exposure is zero. You'll see this done in the walkthrough below.

One thing the Privacy Line is not: a reason to never paste anything. It's a line, not a wall — and section 1 told you why the difference matters. Everything you withhold beyond the line costs you grounding, and grounding is where the accuracy comes from. Paste freely on the safe side; stop at the line.

Analogy · the food processor

Buying a food processor doesn't change what you cook. It changes how long the chopping takes — and it does that every single evening, for years. How much time it gives back depends on what you're making, but the direction is always the same. Nobody writes poetry about a food processor, and nobody who owns one would give it back. The Four Desk-Work Verbs are the four blades: the win isn't one spectacular dinner party, it's every ordinary Tuesday for the rest of the year. And one more thing carries over exactly: you still taste before you serve. The processor does the chopping; the cook still owns the dish. You don't send what you haven't read.

▤ In the tool · the four verbs on your real desk

Four short walkthroughs, one per verb — each on material from your actual life, because that's the entire point of today. Before you start, collect four real things: an email you owe a reply to, a PDF or document you've been avoiding (a contract, a school letter, a report, an insurance doc), your week (fixed commitments + the to-do list), and some messy numbers (last month's expenses copied from your banking app, or any list that needs untangling). Read all four walkthroughs now — but you only have to run one today, the one your practice mission picks. The other three become your repertoire over the next week.

VERB · what you hand itwhere it runs
DRAFT · a real email + your intentyour daily driver
DISTILL · a real PDF or docClaude · the paper-clip
PLAN · commitments + to-dosyour daily driver
TABULATE · messy copied rowsClaude · table in, file out

One convention, used in every prompt from here to Day 10: square brackets mean "replace with your own." [paste the email] is an instruction to you, not text to send.

And here is the Privacy Line in action — ten seconds of editing while you paste:

Before: "Invoice from Anna Weber, IBAN DE89 3704 0044 0532 0130 00, deposit for Hochstr. 12"✗ over the line
After: "Invoice from [Name], IBAN [acct], deposit for [address]"✓ same task, zero exposure

Same prompt, same quality of answer. The assistant never needed the real details — it needed the situation.

Walkthrough 1 · DRAFT — reply to an email you actually owe. In your daily driver.

  1. Open your daily driver and start a new chat (the new-chat button, usually near the sidebar). an empty message box, cursor blinking.
  2. Open the email you owe a reply to and copy its full text. If it contains other people's private details, swap them for placeholders as you go — you saw how above.
  3. Paste it inside this brief:
    Copy-paste promptHere's an email I received: [paste the email] Draft a reply that [your real intent — e.g. says yes to the meeting but moves it to next week]. Keep it warm and under 100 words.
    a reply that answers the actual points in the email — your meeting, your dates, your situation. Not a template.
  4. Now iterate, exactly like Day 2 taught you — in the same thread:
    Copy-paste promptGive me 3 versions: friendly, neutral, firm. Keep each under 100 words.
    three genuinely different tones in seconds. Pick one, tweak a line if you like, read it once, and send it for real.

Walkthrough 2 · DISTILL — make a document you've been avoiding explain itself. In Claude, the file workhorse.

  1. Open claude.ai and start a new chat. We're here for the file powers from Day 3's staff model — the generous upload allowance, and (on most plans) the ability to create files back.
  2. Click the attach button (the paper-clip / + icon near the message box) and choose your real PDF or document. Privacy Line check first: would you email this file to an outside contractor? If yes, attach away. the file's name appears attached above or beside the message box.
  3. Send this with the file attached:
    Copy-paste prompt · ClaudeSummarize this document in 5 bullet points. Then list anything I should be careful about. Then answer: [one question you actually have about it].
    a summary that uses your document's own words and numbers — and an actual answer to your question, drawn from the text.
  4. Now the move most beginners miss: interrogate. Stay in the same thread and keep asking:
    Copy-paste prompt · ClaudeWhere exactly does it say that? Quote the line. And is there any deadline in this document I could miss?
    the assistant pointing at specific passages from the file. That's grounding, live — it's quoting, not recalling.

Walkthrough 3 · PLAN — turn next week from a fog into a schedule. In your daily driver.

  1. Start a new chat. Gather your real week: the fixed commitments (meetings, school runs, appointments) and the list of things that need to get done.
  2. Hand it everything at once:
    Copy-paste promptPlan my week. Fixed commitments: [paste them]. Things I need to get done: [list them]. Build a realistic day-by-day plan with buffer time, and tell me honestly what won't fit.
    a day-by-day schedule — plus an honest "this won't fit" list. That list is the most valuable part; a plan with no overflow is a plan that's lying to you.
  3. Push back. The first plan is a first draft, like every first answer since Day 1:
    Copy-paste promptMornings don't work for focused tasks — move deep work to after 2pm, protect Thursday evening completely, and tell me what you'd drop first if the week goes sideways.
    the plan rebuilt around how your life actually works. Iterate until it's yours, then copy it wherever your week lives.

Walkthrough 4 · TABULATE — from banking-app chaos to a clean table. In Claude.

  1. Copy last month's expenses from your banking app or statements — as-is, ugly formatting and all. Don't tidy anything; untidiness is the assistant's job.
  2. Anonymize as you paste: real account numbers become [acct], names of people become [Name]. Merchant names like supermarkets are fine — they're the useful part.
  3. Send it:
    Copy-paste prompt · ClaudeHere are my expenses from last month, copied as-is: [paste the rows]. Turn this into a clean table by category, total each category, and tell me the top 3 places my money went. If anything is ambiguous, ask me instead of guessing.
    either a clarifying question (answer it — that's the Day 2 "ask me first" instinct working in reverse) or a clean categorized table with totals and a top-3 story you probably suspected but had never seen in numbers.
  4. Two optional finishers, both worth trying once:
    Copy-paste prompt · ClaudeCreate this as a downloadable spreadsheet file. Then explain, in plain language, the formula I'd need to total a category myself in a normal spreadsheet.
    a real file you can download and open — on most plans Claude creates files, not just text — plus a formula explained like a patient colleague would. If you don't get a download link on your plan, ask: "Give me this table as CSV text I can paste into Google Sheets." Same result, one extra paste.
⚠ The common mistake

Pasting like there's no tomorrow. The chat window feels as private as a notes app, so beginners pour everything in: the full contract with both parties' bank details, the screenshot with a password in the corner, a colleague's salary, a friend's medical situation. It isn't a notes app — it's an outside contractor, and the Privacy Line exists precisely so you never have to think harder than that one test: would I email this to a contractor? No passwords, no full card numbers, no other people's private data; anonymize when it doesn't change the task. But notice the mirror-image mistake, because it's just as expensive: being so cautious that you never paste anything — and losing the grounding that makes the assistant accurate, leaving it to recall from memory exactly when you needed it to quote from your text. The people who get this right treat it as a line, not a wall — and they get both the accuracy and the safety. That balance is your edge.

⏱ Practice mission · 10–15 min · your real material

Pick the single most annoying recurring task from your last week — inbox triage, meeting notes, the monthly report, the expense mess. Decide which verb it is (Draft, Distill, Plan or Tabulate); that's the one walkthrough you run end-to-end on the real material, including one round of iteration. Then open your notes app, rename the note you started on Day 2 to Prompt Notebook, and save today's winning prompt — verbatim, with one line on what it was for — as entry #3. Day 2's briefing is already entry #1 and Day 3's daily-driver verdict is entry #2; if you haven't added them yet, fold them in now. Three entries, and a recipe box you'll still be using long after this course ends.
